Linear Regression Model

Model equation:
Yi = α + β × Xi + εi

Top border of price channel:
Exp(Yi) = Exp(a + b × Xi + 2 × s)

Bottom border of price channel:
Exp(Yi) = Exp(a + b × Xi – 2 × s)

where:

i - observation number
Yi - natural logarithm of FIZZ price
Xi - time index, 1 day interval
σ - standard deviation of εi
a - estimator of α
b - estimator of β
s - estimator of σ
Exp() - calculates the exponent of e


Primary Trend

Start date: February 1, 2021
End date: April 29, 2025

a = 3.7688

b = 0.0000

s = 0.0791

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0000) – 1
= 0.89%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0791) – 1
= 37.19%

Top border of price channel:

Exp(Y190)
= Exp(a + b × X190 + 2 × s)
= Exp(a + b × 277 + 2 × s)
= Exp(3.7688 + 0.0000 × 277 + 2 × 0.0791)
= Exp(3.9336)
= $51.09

Bottom border of price channel:

Exp(Y190)
= Exp(a + b × X190 – 2 × s)
= Exp(a + b × 277 – 2 × s)
= Exp(3.7688 + 0.0000 × 277 – 2 × 0.0791)
= Exp(3.6174)
= $37.24

Top border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(3.7688 + 0.0000 × 1,825 + 2 × 0.0791)
= Exp(3.9711)
= $53.04

Bottom border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(3.7688 + 0.0000 × 1,825 – 2 × 0.0791)
= Exp(3.6549)
= $38.66
